U.S. unemployment will peak in the "low- to mid-teens" before falling to about 8% by the end of 2020, Dallas Fed President Robert Kaplan said Thursday.

The new outlook represents the most bearish view on Wall Street, according to the CNBC Market Strategist Survey that rounds up 16 top strategists' forecasts. "Amid the COVID-19 crisis, instead of a V-shaped recovery, we see risks that a lack of a synchronized health care response nationally results in weakened economic activity that drags out into 2H," Savita Subramanian, head of U.S. equity and quantitative strategy at Bank of America, said in a note Thursday. —Li
